Montana, have invented certain new and useful Improvements in Fish- Screens, ofwhich the following is a specification.

t e course of the stream and coming stranded on the land he object of the inventionis to provide a revolving screen, which, when positioned and other floating debris.

further object of the invention is to provide a revolving screen having a water wheel associated therewith and operatively he screen whereby rotation of the water wheel in one direction will of the screen and complished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the folront elevation, partly *1g. 4 is an enlarged- H of Fig. 1.

screen is built, Water or are mounted upon the said a ly in spaced relation and rigid therewith, said wheels, by reason of their di with respect. to the passing stream, being rotatable to drive said shaft 1.

A suitable frame, designated as an entirety y the numeral 5 is positioned to extend parallel With the shaft 1, and slightly in a Vance of the wheels 4, the respective endsof frame being perpaddle wheels 4 shaft I, preferor posts arranged upon stream.

A second shaft 8 1s journaled withbearings 9 depending from the .5, said shaft extending parallel haft 1, motion being imparted thereto through the medium of a sprocket 10 operating over Wheels 11 and 12 01, one upon each of the said shafts h end of the said shaft 8 is mounted a beveled gear 13 meshing into alike gear 14 mounted upon a stud table with and upon the said shafts 19 are positioned, one adjacent each of the respective banks of the stream, it is apparent that the screen 23 which operates thereover, may be made to travel or operate in a direction transverse to the direction of rotation of the paddle wheels 4. Both the shaft 19 and the shaft 20 are journaled at one end inthe frame 5, t eir opposite ends being bearings 24 embedded within concrete blocks bed of th as to engage the GXtGIlOI journaled within said brush being of a length'sufiicient to en I desire to emphasize the fact that various gage the screen from one to the other of its minor changes in details of construction, opposite longitudinal edges. proportion and arrangement of parts may A third vertically disposed shaft 27 is be resorted to, when required, without sacrijournaled at one end within the frame 5 and ficing any 0 the advantages of my invenat its opposite end within a suitablebeartion, as defined in the'appended claims. ing 28 positioned in the bed of the stream, Having thus fully described my invention, the said shaft being disposed forwardly of what I claim as new and desire "to secure by the screen 23 and rotated by means 0 a Letters Patent, is
